FURNACE SNO. 860,466.

Specification of Letters Patent.

Patented July 16, y1907.

To all whom it may concern:

Be it known that we, WILLIAM J. HATCHER and JOHN WALTER CRIM, citizens of the United States, and residents of Johnston, in the county of Edgefield and State of South Carolina, have invented certain new and useful Improvements in Ftnnaces, of which the following is a specification.

Ourinv'ention is an improvement in furnaces, and

consists in certain novel constructions, and combinations of parts hereinafter described and claimed. Referring to the drawing forming a part hereof Figure I is a vertical longitudinal section of my invention. Fig. 2 is a top plan view. Fig. 3 is a perspective view ofthe ring halves and Fig. 4 isa section on the line 4 4 of Fig. 2.,

In the practical application of our invention, we provide a cylindrical casing A provided with a square opening a, through that part of the cylindrical surface which we Will hereafter designate as the front. Lugs a', are arranged on the sides of the casing at the upper edge thereof and are provided with set-screws ai.

A ring C having a mean diameter equal to the dialneter of the casing and comprising the halves c and c Arests upon the upper edge of the casing and each of the halvesis provided with a notched lug c2 for engaging the set screw on the lug on the casing. The inner sides of the adjacent ends of the ring halves are notched as at c3 to receive the ears of a wash pot adapted to rest upon the ring. Loops c4 are secured to the upper faces of theends of one ring half, and are engaged by bars c5 secured to the ends of the other ring half. In placing the ring upon the casing, each half is placed thereon With the ends of the bars engaging the loops, after which the halves are pushed together thus forcing the bars into the loops. The bar passes across the inner part of the opening formed by the notches, thus serving as a support for the ears of the pot. A smoke vent a3 is arranged in the rear face of the casing, and a pipe D is secured to the edges of the vent. A damper (Z may, if desired, be arranged within the smoke pipe.

A fire box E is secured to the edges of the rectangular opening in the front of the casing, by means of angle plates e, and is provided with a grate bar c/ resting upon supports e2 in the interior of the fire box. An

opening e3, is arranged in the free end of the lire box,

and a door e4 hinged to the upper face of the fire box as at e5 is adapted to close the opening of the fire box proper, and is secured in its closed position by a pin c6 sliding in a staple e7 and engaging an eye es on the grate bar.

The space below the g'rate bar may be provided with a damper, or may be left open as desired, and on the upper face of the fire box we provide a circular opening e having thereover a cap el of ordinary construction.

When the wash pot is placed upon the ring, the body of the pot will be almost completely inclosed within the cylindrical casing, only about two inches of the top of the body being visible. The bottom of the pot will reach within about four inches of the bottom of the heat box, leaving only suflicient room for the heat and smoke to pass therearound. The casing is made preferably of sheet metal and the pot supporting ring is preferably of cast iron and about three inches wide, thus leaving about l inches space between the pot and the cylinder, and giving the pot all the benefit of the heat. The ring fits closely around the pot closing the opening between the side of the pot and the side of the casing. The circular opening in the lire box, is adapted to receive an ordinary cooking pot, and the upper surface of the lire box being flat forms an excellent surface for heating irons.

It will be evident that by our construction of furnace We provide an eilicient heating means, requiring but a small amount of fuel and adapted for use in or out of doors. For out of door use it is unnecessary to have a bottoni or casing in the furnace.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is l. In a furnace, the combination with a wash pot of a cylindrical casing i'or receiving said pot, and provided with an opening, lugs on the upper edges of the casing at the sides thereof, set-screws on the lugs, a ring coniprising halves resting on the upper edge of the casing, und provided with notches on the inner sides of the adjacent ends of the ring halves for receiving the ears of the pot, loops secured to the ends of one of the ring halves, hairs secured to the ends of the other ringhalt` for engaging the loops, lugs on the ring halves for engagement by the set-screws, a smoke vent at the rear of the casing, and a lire box secured to the edges of the opening in the casing. I

2. In a furnace the combination with a wash pot ot' a cylindrical casing for receiving said pot and provided with an opening, u ring comprising halves resting on the upper' edge of the casing and provided with notches on the inncr sides of adjacent ends of the halves for receiving the curs of the pot, means for adjustably securing the ringr to the casing, loops secured to the ends of one ol' the ring halves, bars secured to the ends of the other ring half for engaging the loop, a smoke vent at the rear of the casing, and a tire box secured to the edges of the casing.

3. In a furnace, the combination with a wash pot of a cylindrical casing for receiving said pot, provided with an opening in its front, a two part ring resting on the upper part of' the casing and provided with openings for receiving the cars of the pot, means for adjnstubly securing the ring to the casing, means for adjusting the parts of the rings with respect to each other, a smoke vent in the casing, u tire box secured to the edges ol' the openings in the casing.

4. In a furnace, the combination with a wash pot of :L cylindrical casing for receiving said pot, and provided with au opening in its front, a two part ring resting on the edges of the casing, means for adjustably securing the ring to the casing, means for adjusting the parts of the ring with respect to euch other, a smoke vent in the casopening in the casing, and a grate bar supported-Within the nre box.

In a furnace, the combination. with a wash pot of a cylindrical casing for receiving a pot, a two part ring resting on the upper edge of the casing for supporting the pot, means for adjusting the parts of the ring to close the opening between the pot and the casing, a smoke vent in the rear face of the casing, a fire box securedA to;the front of the casing, and communicating therewith, and a door hinged to the free end of the-fire'box.

6. In a furnace, the combination with a Wash pot of a cylindrical casing -for receiving said pot, a two part ring resting on the upper edge of the casing; means for adjusting the parts of the ring with respect to eachy other, a smoke vent at the rear of the casing, a re box at the front of the casing,.and communicating therewith, and a grate bar supported within the re box,

7. In a furnace, the combination with a wash pot of the casing for receiving said pot, meanson the casing for supporting the pot, means for adjusting the supportingmeans for different sized pots, a smoke vent in the casing, and a fire box at the opposite side of the casing from the smoke vent and communicating with the casing.

S. 1n a furnace, the combination with a Wash pot of the casing, means on the casing for supporting the pot,

means for adjusting the supporting means to close the opening between the casing and' the pot, a smoke vent on one side of the casing, and a re box at the opposite side :of the casing and communicating therewith.

9. In a furnace, the combination with'a pash pot of a cylindrical casing for receiving the pot, means resting on the upper edge of the casing for supporting the pot and Vcomprising a two part ring, means for adjustably secur- 4ing the r-ingrto the casing, and means for adjusting the 4parts of the ring towards and from each other.

l0. In a furnace, the combination with a Wash pot, of a casing for receiving said wash pot, means resting on the upper edge of the casing for receiving the pot, and comprising a two part ring, and means for adjusting the parts of the ring towards and from each other.

11. In a furnace, the combination with a wash pot having oppositely arranged ears, of a casing for receiving the po't, and a ring for supporting the said, pot resting upon the edge of the casing and having means for en gaging the ears.
